The more I read about it, it makes me wonder how all of these are connected.

My theory is that somehow, the intake plenum boots got detached upon start up with the new battery. Maybe there was too much gas vapor inside the engine during the hard cranking when the car was being started using the old weak battery or perhaps during the jump start. The excess vapor when combusted might have produced sufficient pressure to 'blast' out the plenum boots.

Why is there now a fault code 412? My guess is that the 'explosion' could have messed with the throttle jacking sensor and/or the throttle body. Or maybe the throttle body is just really dirty.

I am inclined to think that the problem is mechanical (well, the throttle jacking sensor is of course electronic but it may have been damaged physically) because of the 'explosion', and not the electronic failure of the DME.

I've got an engineering degree...but in a completely different field so I wouldn't be surprised if everything I've just said is pure nonsense to the technically minded!

So I would appreciate any help you guys can offer. I just need to know a starting point on which parts to order. My car is in Manila so I need to source parts online and take to account the longer shipping time.

Thanks y'all!
